Rainbow King: An overlooked masterpiece from Novomatic

Where to play Rainbow King

Overshadowed – and unfairly in our opinion – by its close relative Reel King, Novomatic’s Rainbow King also needs to be looked at closely by anyone interested in some genuinely addictive pub fruit slots action.

What makes Rainbow King so popular?

One of the ‘Reel King’ series of slots, Rainbow King is a genuine pub fruit-style slot, which partly explains its popularity: In a world increasingly dominated by fancy 3d visuals and branded themes the importance of good quality gameplay is often neglected – but not on games like this.

It has 5 reels and a manageable 20 paylines and a self-explanatory wild symbol; however, you also get 3 different bonus rounds:

Get 3 or more of the Castle scatter symbol and you’ll be given a classic-style ‘pick me’ tombola bonus round which in this case remains on screen: You simply select one of your own scatter symbols and it will reveal a cash prize. 

The second bonus feature is triggered by the 3 or more of the ‘Crown and Jewels’ symbol. This time you will be taken off-screen, to another ‘pick me’ round with 12 crowns: Pick one of them to reveal the size of your prize.

The third bonus feature is activated by yet another scatter function, so if you like scatters you’ll love this game. This time it’s the game symbol, and 3 or more of the ‘Rainbow King’ anywhere on the reels takes you to a pub-style trail feature, which is the key draw in this game. You’ll be taken to a new screen showing a game board and die, which you’ll roll to move your piece round the board. Jewel squares awarded you a prize; Joker squares take you to another square on the board. If you land on the ‘Rainbow King’ square you will activate a mini slots game that will be played at the end of the game. If you land on ‘Take the Money’ the feature ends.

It’s this third bonus feature that really sets Rainbow King apart: All true slots devotees love a good trail feature, yet amazingly most online slots designers seem to omit them and we can’t figure out why. After all, Monopoly is the most successful online slot of all time, spawning 3 sequels – and it has one, as do a few other hugely popular games. We hope they build more of them into future games, but for now this little belter from Novomatic is a great way to get your fix so keep playing it and see how many times you can make it round the board.

How much can I win on Rainbow King?

There’s a top jackpot of £15,000 on this game at most casinos, though it can be altered at each casino’s discretion.

How volatile is Rainbow King?

This game has an RTP of 95% and has low to medium volatility.

That means popular TV shows, board games and the like are here in abundance, though given their presence in service stations, bookmakers and other land venues in the UK it’s no surprise to see Novomatic slots on offer too. 

    Sky Vegas have access to the Murdoch empire resources, meaning they can superior customer service, better hardware, quicker payouts – and bigger bonuses.
